i Application ledSeptember 26, 1902. Serial Nu.'124,969. (No model.)

To atl whom t may concern:

- Be it known that I, ROBERT P; WHEELEm a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inProcesses of Mounting Photographs, Pictures, &c.; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof.

My invention relates to an improved process for mounting photographs,pictures, and the like; and it consists in the several steps set forthand subsequently claimed.

The accompanying drawings indicate the main steps of my said process, ashereinafter set forth, the thicknesses of the several strata beingexaggerated for sake of clearness.

Figure 1- 'of said drawings represents a gutta-percha film; Fig. 2, apiece of thin paper; Fig. '3, an unmounted photograph, picture, or likeobject; Fig. 4, a thick cardboard mount; Fig. 5, a series of alternatesheets of film and thin paper; Fig. 6,. a film with the photograph orlike object on top of the same and a sheet of thin paper below; Fig. 7the said film with the sheet of thin paper shifted to the top andreplaced by a cardboard-mount at the bottom of the strata; Fig. 8, thesame strata with a heated iron pressing thereon, and Fig. 9 thecompleted mounted object with the iron and sheet of thin paper removed.A

I first take pure gutta-percha and dissolve the same in carbon disulfidand pour the solution upon a smooth surface (where it rapidly begins toharden) and roll the same into a large sheet or film of uniformthickness not exceeding the one one-thousandth of an inch. I next cutthis large sheetinto smaller sheets, preferably of. about twenty-four bythirtysix inches, Fig. 1, and place a sheet of ythin print-paper., Fig.2, between each two adjacent sheets of the gutta-percha film, so thatthe whole is arranged in alternate layers of film and paper, Fig. 5,.and then I again cut the sheets without disturbing the layers intostandard sizes that correspond with the sizes of photographs `taken bythe diderent cameras in use. I next take the stiff cardboard or othermount, Fig. 4, on which a photograph is'to'be mountedand take up saidphotograph, Fig. 3, and apply to the under side thereof a film of propersize, with lthe sheet of print-paper still beneath said film, and trimthese three sheets (print-paper, film, and photograph) together, so thatthe' edges are all even with each other, Fig. 6. Then I separate thefilm from the print-paper and the photograph and place said film on themount in the proper position or location that the photograph is tooccupy and place the photograph upon the lm and the print-paper on thephotograph, so that the edges of the three strata will all register witheach other, as before, but now with the print-paper on top, Fig. 7 NextI heat an (preferably metallic) article having a smoothbearing-surface-such as afiat-iron, for example-to `the requiredtemperature-say from 150O to 20()O Fahrenheit-and press the smoothheated surface upon the print-paper and strata beneath, Fig. 8, for avery short time-say fifteen seconds, more or less-and then remove thesheet of print-paper, and the photograph will be found to be firmly andsmoothly secured to the mount, Fig. 9. In place of the hot flat-ironheated rollers or other smooth heated surfaces may be employed; but thedescribed heated fiat-iron is found to give excellent results, and thepressure can be regulated by the hand of the user, as found desirable inpractice.

While I have referred in this description to the mounting ofphotographs, (which is the principal object of the inventon,) it will beunderstood that it is equally as effective for thesmooth unwrinkledmounting of any similar thin objects, such as etchings, engravings,prints, or other pictures, or thin sheets of printed or engraved matterof any sort, or the like.

Having thus described myv invention, what I claim as' new, and 'desiretosecure by Letters Patent, is-

1. The herein-described process of mounting photographs, pictures andthe like consisting in alternating sheets of gutta-percha n films andthin paper and cutting same collectively to the desired size; next,taking one of these gutta-percha films, with the paper beneath the same,and placing a photograph, picture, or like object upon the upper surfaceof the said lrn, and making the edges of all Coincide; then, shiftingthe thin paper from the bottom to the top of the strata, andsubstituting a mount for the said paper as the bottom layer; neXt,subjecting the Whole strata to the action of heat and pressure, andfinally removing the thin paper, leaving the photograph, picture orother like object firmly united to the mount by the interposedgutta-percha film.

2. The herein-described process of mounting photographs, pictures, andthe like, consisting inr the following steps in the order named; first,dissolving pure gutta-percha in carbon disulfid; second, pouring thesolution upon a smooth surface, and vletting it remain there until itbegins'to harden; third, rolling the same into a large sheet or film of'uniform thickness, not exceeding the one onethousandth of' an inch;fourth, removing said film from the said smooth surface, and cuttingthis large sheet into smaller sheets; fifth, placing a sheet of' thinprint-paper between each two adjacent sheets of the gutta-percha films,and again cutting the said sheets, without disturbing the layers, intosmaller stand-- ard sizes; sixth, taking a photograph, picture, or otherobject to be mounted, and applying to the under side thereofl a film ofgutta-percha with the sheet of' print-paper still beneath said film, andtrim said three sheets (of print-paper, filmwand photograph or otherobject) together, so that their edges are all even with each other;seventh, separating the film from the print-paper, and from thephotograph or other object; eighth,

taking asti-H cardboard or similar mount, and placing the said filmthereon; ninth, placing the photograph or other object to be mountedupon said film; tenth, placing the said'print-paper upon the saidphotograph or other object, so that the edges of the film, photograph orother object, and print-paper, shall all register, as before, but withthe print-paper now on top, and the mount at the bottom, and eleventh,subjecting the Whole strata tothe action of heat and pressure.

4In testimony that I olaimthe foregoing 1 have hereunto set my hand, atChicago, in the countyof' Cook and State of Illinois, in the presence oftwo witnesses.
